Definitions
- the present invention relates to an instrument panel reinforcement structure for motor vehicles.
- the reinforcement structure extends between two front pillars and supports a steering column, a glove box, a passenger side air bag and various other instrument panel components.
- the instrument panel reinforcement structure is the part of a motor vehicle extending between left and right front pillars in front of the passenger compartment.
- Various components mounted on the instrument panel reinforcement structure include the steering column assembly, a glove box, a passenger side air bag, an instrument cluster, an entertainment/information system, a heating/ventilation/air conditioning unit with associated ducts, a wire harness, electrical modules and fascia.
- the inclusion of driver side air bags and the locating of some controls in the steering column assembly have caused it to gain weight and to grow in size.
- Onitsuka U.S. Pat. No. 4,560,186 describes an automobile instrument panel assembly supported by a reinforcement 4 comprising a pipe 5 extending between two pillars 3 .
- the pipe has a uniform size in the cross-car direction.
- a steering column mounting bracket made up of metal sheets is welded to the pipe 5 on the right (driver's) side.
- Onitsuka's assembly is difficult to manufacture economically because it includes so many individual parts welded to the pipe 5 . Accordingly, there still remains a need for a stiff, light weight, economically manufacturable instrument panel reinforcement structure.
- a principal objective of our invention is to provide a light weight instrument panel reinforcement structure for motor vehicles that has enhanced structural stiffness in order to minimize steering column vibrations.
- a related objective of the present invention is to provide an instrument panel reinforcement structure for motor vehicles made from aluminum alloy and magnesium alloy components.
- the reinforcement structure of the present invention offers about a 40% weight saving compared with similar systems having steel components.
- the preferred reinforcement structure shown and described herein weighs only about 18 pounds (7.7 kg).
- Another objective of the invention is to provide a light weight instrument panel reinforcement structure that consumes little additional cockpit space and is inexpensive to manufacture and to install on a mass production assembly line.
- a further objective of our invention is to provide an instrument panel reinforcement structure that adapts easily to left and right hand drive cars and accommodates different steering column orientations.
- a light weight instrument panel reinforcement structure for inclusion in a motor vehicle body having a floor panel and several pillars extending upwardly from the floor panel.
- the reinforcement structure extends between the left and right front pillars in front of the passenger compartment.
- the reinforcement structure supports a steering column, a glove box, a passenger side air bag and various other instrument panel components.
- a preferred instrument panel reinforcement structure comprises a passenger side cross tube and a driver side cross tube connected by a center stack support.
- the cross tubes are preferably connected to the front pillars through metal brackets.
- the center stack support is preferably connected to the floor panel.
- Mounting tubes attached to the driver side cross tube support the steering column.
- the passenger side air bag support is attached to the passenger side cross tube.
- a driver side knee bolster is connected to the driver side cross tube through metal crush tubes.
- Metal crush tubes also connect a glove box door frame to the passenger side cross tube.
- the driver side cross tube and the passenger side cross tube are preferably aluminum alloy extrusions.
- Aluminum alloys of the Aluminum Association (AA) 6000 series are preferred although other alloys may also be used.
- the AA 6000 alloys including AA5000 series alloys generally contain about 0.2-2 wt. % silicon and about 0.2-2 wt. % magnesium. These aluminum alloys usually also contain other alloying elements and some impurities.
- Our particularly preferred cross tubes are made with an AA 6063 T4 alloy containing about 0.2-0.6 wt. % Si, 0.45-0.9 wt. % Mg, 0.35 wt. % max. Fe, 0.10 wt. % max. Cu, Cr, Zn and Ti, remainder Al, incidental elements and impurities.
- a particularly preferred driver side cross tube is extruded as a hollow oval having a 120 ⁇ 60 mm cross-section with an average 5 mm wall thickness.
- the extruded cross tube is hydroformed in a middle portion to provide a generally triangular cross section with a flat bottom surface appropriately oriented for attachment of two steeling column support tubes.
- the cross tube also includes two openings for crush tubes contacting a driver side knee bolster.
- the steering column support tubes are preferably AA 6063-T4 aluminum alloy extrusions having a wall thickness of about 5 mm.
- a particularly preferred passenger side cross tube is a hollow cylinder having an outer diameter of about 60 mm and a wall thickness of about 3 mm.
- the driver side cross tube and the passenger side cross tube both extend laterally or in a cross-car direction, on opposite sides of a center stack support.
- An important feature of our invention is that the driver side cross tube has greater average wall thickness than the driver side cross tube. outwardly of the center stack support and a first wall having a thickness that is generally constant across the first length.
- the driver side cross tube has a second length extending laterally outwardly of the center stack support and a second wall having a thickness t 2 that is generally constant across the second length.
- the driver side cross tube is preferably reformed by a process that includes pressurizing the tube internally with an incompressible fluid at sufficient pressure to deform the middle portion inside a die.
- the incompressible fluid is preferably water at a pressure of about 100-5,000 psi, more preferably about 1,000-3,000 psi.
- a die outside the middle portion and the pressurized water force the middle portion into a generally triangular cross section while the end portions retain their original, oval cross-sectional shape.
- the hydroformed driver side cross tube still has continuous internal and external surfaces.
- the generally triangular middle portion has a larger radius of gyration than the end portions. Accordingly, the driver side cross tube has excellent resistance to twisting, even after a steering column is attached. The triangular middle portion also has greater resistance to vibration than the end portions.
- the center stack support is preferably a magnesium alloy casting having a complex shape that includes several walls having an average thickness of about 2.5 mm.
- the center stack support includes a first sleeve defining a first opening for the first wall on the passenger side cross tube, and a second sleeve defining a second opening for the second wall on the drivel side cross tube.
- Each sleeve includes several ridges extending radially inwardly of the sleeve wall.
- the sleeve walls, ridges and tube walls, in combination, define spaces for a polymeric adhesive binding the cross tubes to the center stack support.
- the crush tubes are preferably cold drawn from an AA 6000 alloy, more preferably an AA 6061 T4 alloy.
- the crush tubes have an outer diameter of about 30 mm and a wall thickness of less than about 1.0 mm and about 0.7 mm in a particularly preferred embodiment.
- the crush tubes are inserted into openings in the cross tubes and then welded around the openings.
- the crush tubes preferably include one or more circumferentially extending buckle initiators that are preferably mechanically formed indentations extending around the entire circumference. The buckle initiators facilitate folding of the crush tubes in an accordion-like manner when impact occurs with an occupant's knees.
- the knee bolster is preferably made from aluminum alloy sheets.
- a particularly preferred knee bolster includes a generally planar first metal sheet and a second metal sheet defining several cup-shaped indentations. The indentations have generally flat portions adjacent the first metal sheet. Additional details of construction of a particularly preferred knee bolster are shown in Seksaria et al. U.S. Pat. No. 5,244,745 issued Sep. 14, 1993 and entitled “Structural Sheet and Panel”, the disclosure of which is incorporated by reference to the extent consistent with the present invention.
- Two other crush tubes connect the passenger side cross tube with the glove box door frame.
- a glove box door hinged to the frame acts as a knee bolster on the passenger side.
- End portions of the passenger side and driver side cross tubes are attached to front hinge pillars through metal end brackets or bracket means.
- the end brackets are preferably stamped from aluminum alloy sheet material having a thickness of about 4 mm.
- the end brackets are welded to the cross tubes and then attached to the hinge pillars by metal fasteners extending through openings in both the brackets and in the hinge pillars.

- the instrument panel reinforcement structure of our invention comprises a secondary structure attached to a motor vehicle body 20 , as shown in FIG. 1 .
- the vehicle body 20 includes a floor or floor panel 22 , right and left front pillars 23 , 24 , right and left middle pillars 25 , 26 and right and left rear pillars 27 , 28 .
- the pillars 23 , 24 , 25 , 26 , 27 , 28 extend upwardly from the floor 22 , supporting a roof 30 .
- the reinforcement structure extends between the two front pillars 23 , 24 and supports a steering column, a glove box, a passenger side air bag and various other instrument panel components. Some of the instrument panel components may be covered with plastic, wood or leather fascia (not shown).
- the structure 18 includes a center stack support 35 connected on lateral sides with a passenger side cross tube 37 and a driver side cross tube 39 .
- the center stack support 35 is a magnesium alloy casting.
- the passenger side cross tube 37 and the driver side tube 39 are hollow, aluminum alloy extrusions.
- the passenger side cross tube 37 has a laterally extending first wall 41 and the driver side cross tube 39 has a laterally extending second wall 43 .
- the passenger side cross tube 37 has a right end portion 46 connected to a right hinge pillar bracket 47 .
- the driver side cross tube 39 has a left end portion 48 connected to a left hinge pillar bracket 49 .
- the brackets 47 , 49 each define through openings 51 , 53 for bolts (not shown) or other through fasteners connecting the brackets 47 , 49 to the front pillars 23 , 24 .
- the center stack support 35 includes a pair of bottom flanges 54 , 55 each defining through openings 56 for bolts (not shown) or other through fasteners for connecting the support 35 to the floor 22 .
- the passenger side cross tube 37 is a generally cylindrical aluminum alloy extrusion having a laterally extending first wall 41 .
- the cross tube 37 is made from an AA6063 T4 aluminum alloy.
- the cross tube 37 has an outer diameter of about 60 mm (2.4 inches) and the first wall 41 has a thickness of about 2.8 mm (0.11 inch).
- the cross tube 37 has a right end portion 46 welded to the right hinge pillar bracket 47 and a left end portion 69 nested in a first sleeve 60 on the center stack support 35 .
- the sleeve walls 60 , 61 each include several radially inwardly extending ridges 70 .
- the ridges 70 abut against walls 41 , 43 of the tubes 37 , 39 .
- Connections between the sleeve walls 60 , 61 and the tube walls 41 , 43 are also stabilized by through fasteners (not shown).
- a bolt or other through fastener extends through an opening 63 in the center stack support sleeve 61 and through the wall 43 of the driver side cross tube end portion 84 .
- the sleeve walls 60 , 61 combine with the ridges 70 and tube walls 41 , 43 to form several pockets 72 for an epoxy adhesive.
- One important advantage of our invention is that the adhesive in pockets 72 dampens vibrations transmitted through the center stack support 35 to the driver side cross tube 39 . Accordingly, vibrations transmitted by the reinforcement structure 18 to the steering column assembly have reduced intensity compared with an instrument panel reinforcement structure including only a single tube extending between the front pillars 23 , 24 .
- the passenger side cross tube 37 defines two pairs of aligned holes 74 , 75 .
- Each pair of holes 74 , 75 accommodates a crush tube 78 attached to a glove box door frame 80 , as shown in FIG. 2 .

- the cross tube 39 is made from an AA6063 T4 aluminum alloy.
- the cross tube 39 has end portions 82 , 84 that are generally oval in transverse section with outer dimensions of about 120 mm ⁇ 60 mm.
- the left end portion 82 is welded to the left hinge pillar bracket 49 and the right end portion 84 is attached to a sleeve 61 in the center support 35 .
- the cross tube 39 is formed with two laterally spaced holes 86 , 87 for crush tubes 78 supporting the driver side knee bolster 90 . As shown in FIG. 5A, the cross tube 39 is hydroformed so that a middle portion 83 between the end portions 82 , 84 has a generally flat bottom surface 92 . Two steering column assembly support tubes 94 , 95 are secured to the bottom surface 92 by a combination of metal bolts and adhesive bonding.
- cross tubes 37 , 39 are manufactured from hollow, generally cylindrical aluminum alloy extrusions. These closed aluminum alloy shapes provide excellent stiffness in a small volume, with less weight than steel. In addition, spanning the car width with two separate cross tubes rather than only one concentrates greater strength and stiffness in the driver side cross tube 39 , with greater wall thickness than the passenger side cross tube 37 .
- the term “average thickness” refers to the thickness of a wall in a metal extrusion, averaged around its entire periphery and across its entire length.
- the first wall 41 in the passenger side cross tube 37 has an average thickness, t 1
- the second wall 43 in the driver side cross tube 39 has an average thickness, t 2 .
- the second wall's average thickness, t 2 is preferably at least 25% greater than t 1 , more preferably at least 50% greater, and optimally at least 60% greater.
- the first wall 41 has an average thickness of about 3.0 mm and the second wall 43 has an average thickness of about 5.0 mm, so that t 2 is approximately 67% greater than t 1 .
- the hydroformed driver side cross tube 39 has a generally triangular cross-section in the middle portion 83 and a generally oval shape in the end portions 82 , 84 .
- the middle portion 83 has a larger radius of gyration than the end portions 82 , 84 . Accordingly, the cross tube 39 resists twisting more effectively after a steering column is attached.
- the crush tube 78 has a generally cylindrical wall 98 having an outer diameter of about 30 mm and a thickness of about 0.7 mm.
- a front end portion 99 is attached to one of the cross tubes 37 , 39 and a rear end portion 100 is attached to the glove box door frame 80 or the knee bolster 90 .
- a portion of the wall 98 is crimped to form an area 105 of reduced diameter that acts as a buckle initiator in frontal collisions.
- the support tube 94 has a top wall 110 and a bottom wall 111 interconnected by side walls 112 , 113 .
- the top wall 110 defines two apertures 115 a, 115 b aligned with apertures 116 in the bottom wall 111 , for two metal bolts or other through fasteners (not shown) connecting the bracket 94 to the driver side cross tube 39 .
- the support tubes 94 are bonded to the cross tube 39 by an adhesive layer (not shown) between the bottom wall 92 of the cross tube 39 and the top wall 110 of the support tubes 94 .
- the top wall 110 also defines two other openings 115 c, 115 d aligned with openings (not shown) in the bottom wall 111 , for connecting the support tube 94 to a steering column assembly.
- the support tube 94 is a 6063 T4 aluminum alloy extrusion having a wall thickness of about 5 mm (0.2 in). We avoid welding the steering column support tubes 94 to the driver side cross tube 39 in order to avoid weakening the metal in both components.
